+- 2026-09-25, task 01, third session: the fix was complete and all three tests passed, but the
+  session measured the proxy package failing 7 of 20 runs and went looking for the cause,
+  ending its turn on a refused `/tmp` copy (fifth refusal-ending tonight). The owner ran the
+  package 12 times on an idle machine: 0 failures. The flakes were CPU contention from the
+  model's own inference on the same host hitting the timing-based tests (queue, spread, cancel).
+  Two faults: timing margins in the given tests are too tight for a loaded machine (owner's test
+  design — widen in v2.1 or run those tests with a retry), and the model again ended a turn on a
+  refusal. A fourth session was told to skip the investigation and finish steps 4–7.
